RISC-V Is Thriving: Here’s What You Need to Know
By Steve Brown - 03 Nov, 2022 - Comments: 0

RISC-V, the open-standard Instruction Set Architecture (ISA) conceived by UC Berkeley developers in 2010, is going from strength to strength. The RISC in RISC-V stands for Reduced Instruction Set Computer, meaning it’s designed to simplify each individual instruction given to the computer. As RISC-V is an open standard, anyone can implement, customize, and expand the ISA to suit their r... » read more

A new technical paper titled "Risky Translations: Securing TLBs against Timing Side Channels" was posted by researchers at Ruhr University Bochum (Germany) and Cyber-Physical Systems of the German Research Center for Artificial Intelligence (DFKI). Abstract: "Microarchitectural side-channel vulnerabilities in modern processors are known to be a powerful attack vector that can be utilized to... » read more

Bug-Free Designs
By Brian Bailey - 27 Oct, 2022 - Comments: 0

It is possible in theory to create a design with no bugs, but it's impractical, unnecessary, and extremely difficult to prove for bugs you care about. The problem is intractable because the potential state space is enormous for any practical design. The industry has devised ways to handle this complexity, but each has limitations, makes assumptions, and employs techniques that abstract the p... » read more

5 Good Things About RISC-V
By Filip Benna - 27 Oct, 2022 - Comments: 0

RISC-V has been around for some time now, and if you are here it’s because you have heard of it. But perhaps you still need to be convinced that it is the future? If you still wonder about its potential and benefits, here are five good things about RISC-V. 1. RISC-V is an open standard Let’s start simple. This is nothing new, but let’s be clear on what open standard means. Open stan... » read more

Hardware Trojan Inserted Inside A RISC-V Based Automotive Telematics Control Unit
By Technical Paper Link - 21 Oct, 2022 - Comments: 0

A new technical paper titled "On the Feasibility of Remotely Triggered Automotive Hardware Trojans" was written by researchers at Georgia Tech. "In this paper, we discuss how Hardware Trojans can act as the physical access intermediates to allow the remote triggering of malicious payloads embedded in ECUs, through seemingly benign wireless communication. We demonstrate a proof of concept ECU... » read more

A new technical paper titled "Advanced Embedded System Modeling and Simulation in an Open Source RISC-V Virtual Prototype" was published by researchers at DFKI GmbH and University of Bremen. Abstract "RISC-V is a modern Instruction Set Architecture (ISA) that, by its open nature in combination with a clean and modular design, has enormous potential to become a game changer in the Internet o... » read more

IC Architectures Shift As OEMs Narrow Their Focus
By Ed Sperling - 03 Oct, 2022 - Comments: 0

Diminishing returns from process scaling, coupled with pervasive connectedness and an exponential increase in data, are driving broad changes in how chips are designed, what they're expected to do, and how quickly they're supposed to do it. In the past, tradeoffs between performance, power, and cost were defined mostly by large OEMs within the confines of an industry-wide scaling roadmap. Ch... » read more

Framework Based on an RISC-V Microprocessor Supporting LiM Operations
By Technical Paper Link - 29 Sep, 2022 - Comments: 0

A new technical paper titled "RISC-Vlim, a RISC-V Framework for Logic-in-Memory Architectures" was published by researchers at Politecnico di Torino (Italy), Univerity of Tor Vergata (Italy), and University of Twente (The Netherlands). Abstract: "Most modern CPU architectures are based on the von Neumann principle, where memory and processing units are separate entities. Although processin... » read more

Toward Domain-Specific EDA
By Brian Bailey - 26 Sep, 2022 - Comments: 0

More companies appear to be creating custom EDA tools, but it is not clear if this trend is accelerating and what it means for the mainstream EDA industry. Whenever there is change, there is opportunity. Change can come from new abstractions, new options for optimization, or new limitations that are imposed on a tool or flow. For example, the slowing of Moore's Law means that sufficient prog... » read more

Collaboration Leading The Way For Broad RISC-V Adoption
By Mike Eftimakis - 22 Sep, 2022 - Comments: 0

We recently announced a partnership with Intel as part of the launch of the Intel Pathfinder for RISC-V, making leading RISC-V technology more accessible for prototyping, production design or research purposes using Intel FPGAs. Intel Pathfinder for RISC-V allows for a variety of RISC-V cores and other IP to be instantiated on FPGA platforms, with the ability to run industry-leading oper... » read more
